초록

Recently, inkjet technology has emerged as one of the most powerful tools for patterning
electronics devices, such as large area display applications, RFID, PCB patterning, etc. By using
the Inkjet technology, the droplet speed as well as the size can be controlled precisely. In this
paper, the relationship between waveform and droplet size will be investigated by means of
experiment. Also the relationship between inkjet speed and droplet size will be discussed. It was
shown from experimental results that ink droplet size from the nozzle diameter of 50 μm can be
varied from 37 to 58μm by modifying the inkjet waveform when the speed of the droplet is 1m/sec.
Finally, experimental results indicate that small drops are more difficult to generate than large
drops since the jetting conditions for making small drops are sensitively affected by the dwell time
variation.
